CHARLES TRAXLER, OF AKRON, OHIO, ASSIGNOR TO THE AMERICAN HARD RUBBER COMPANY, OF NEIV YORK, N. Y,

CORRUGATING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 628,564, dated July 11, 1899.

Application led May 11, 1899. Serial No. 716,405. (No model.)

To @ZZ whom it may concern: the sheet and are preferably hinged loosely Be it known that I, CHARLES TRAXLER, a to the chain-links c and o', as shown in detail citizen of the United States, residing at Akin Fig. 4; but it may in some cases be advanron, in the county of Summit and State of tageous to fasten them rigidly to one link at 5 Ohio, have invented certain new and useful each end of the bars. A weight W having 55 Improvements in Corrugating-Machines, of a smooth flat bottom is adapted to slide on which the following is a specification, the the base-plate between the guides g and g. principle of the invention being herein eX- To operate the device, the flexible chain plained and one mechanical form embodying die O is raised up from the grooved base and 1o the invention set forth, so as to distinguish it may be doubled back, so as to rest upon the 6o from other inventions. weight, as shown in Fig. l, if desired. A

My invention relates to machines which are sheet P of the material to be corrugated is employed for corrugating or crimping sheets laid upon the grooved base, the chain die is of metal, hard rubber, or any material which brought down onto it, and then the weight can be made capable of being bent and re- W is moved forward over the rollers 7', forc- 65 ceiyinga durable set.` Its objects are to pro'- ing them consecutively into the grooves, as vide a machine which may be operated either shown in Fig. 2, after which the weight is reby hand or other power and which,beginning turned to its original position against the at one end of a sheet, will quickly and easily stops, and the corrugated sheet is taken out.

2o make the convolutions consecutively, hold- Itis obvious that this device is especially 7o ing the corrugated portion of the sheet firmly suitable for corrugating sheets of normally in place, while permitting the remaining porbrittle material, which it is necessary to heat tion to be taken up as fast as it is bent, thus in order to render it pliant, for having moved obviating the danger of either fracturing or the weight forward to the position shown in stretching the sheet, as between the ordinary Fig. 2 it may be allowed to rest upon the sheet 75 form of grooved dies, through its inability to until the latter becomes cool, when it will retake up, and also preventing the tendency of tain the desired shape of the convolutions and the corrugated sheet to curl, as it does when have no tendency to curl up at the ends. passed between grooved rolls or between a Other modes of applying the principle of fiat and a rolling die." I attain these objects my invention may be employed for the mode 8o by the mechanism illustrated in the accomherein explained. Change may be made as panying drawings, in which. regards the mechanism thus disclosed, pro- Figure l is a sectional elevation of the mavided the principles of construction set forth chine. Fig. 2 is a sectional elevation showand claimed by me are employed.

ing the relative position of the parts of the I therefore particularly point out and dis- 85 machine when the sheet has been corrugated. tinctly claim as my invention- Eig. 3 is a plan view of Fig. 2. Fig. 4 is a del. A corrugating-machine consisting of a tail, partly in section, of a joint between a base provided with suitable grooves, iieXible crimping-rod and its links. Fig. 5 is an edge chains each hinged at one end to the base and 4o view of a corrugated sheet. carrying bars which are adapted-to match said 9o The reference-letter B indicates a basegrooves, and a weight having a fiat bottom plate which is provided with properly-shaped fitted to slide over the chain-bars and force grooves h to iit the corrugations to be made them into the grooves, substantially as set in the sheet. Hinged to the base at u. and a' forth.

is a iieXible corrugating-die C, composed of 2. The combination in armachine for cor- 95 the chains c and c', between which and eX- rugating sheets, of a base-plate having suittending across. the base, as in Fig. 3, are a able grooves in its upper face, flexible chains number of rods or rollers r. These rods are each pivoted at one end to the base, bars conmade of the proper diameter and distance necting the chains and adapted to register 5o apart to suit thecorrugations to be made in with the grooves in the base, and means for roo 1o rollers consecutively into the grooves and retaining them therein during the requisite in; terval, substantially as set forth.

In testimony whereof I adix my signature, in the presence of two Witnesses, at Akron, Ohio, May 8, 1899.
